Question

I'm trying to calculate and report the distance (link-length) between specific agentsets in NetLogo? Is there a way to calculate link length into a list?

The movement of the agents is based on whether the distance(connection) value is below/above a threshold. However, I'm having difficulty setting the values of the link length to variable connection. (preferably in a list). I'd appreciate any help.

globals[hourly-wage connection]
breed[offices office]
breed[employees employee]
offices-own [
  pay-high ;; 7 offices pay well
  pay-low  ;; 3 offices dont pay well
]
to setup 
  clear-all
    create-offices 10 [
    set size 1.0
    set color blue
    set shape "house"
    setxy random-xcor random-ycor
    ask offices [create-link-with one-of other offices] ;; undirected links
    ask links [set color red]
  ]

  create-employees 2 [
    set size 1
    set color brown
    set shape "person"
  ]
  set hourly-wage 20
end

;;;; 
 to go
  cal-dist
  ask employees [ 
    if connection > 15
   move-to one-of high-pay office
    if connection <= 15
    move-to one-of low-pay office
  ]
end

to cal-dist
  set connection [list print link-length] ;; 
  ask links [show link-length]
  set salary (hourly-wage * connection)   ;;; salary printed in a list
end

Not exactly sure what you're trying to do here with connection etc, but you can put any link variables into a list using of- for example:

to setup
  ca
  ; First create the agents
  crt 5 [
    while [ any? other turtles in-radius 5 ] [
      move-to one-of neighbors
    ]
    set color blue
    set shape "house"
  ]

  ; Once they're created, have them link with
  ; one of the other agents
  ask turtles [ 
    create-link-with one-of other turtles [
      set color red
    ]
  ]

  let link-lengths [ link-length ] of links

  print link-lengths

  reset-ticks
end

I don't know that this actually answers your question, so you may want to provide more detail as to what you're trying to accomplish with these links.

How does one report the distance between links and use those values reported for other calculations in code?
